    I used a fuel injection additive called 44k, regular use for two days, the service engine light has gone off, no missing, runs great!

    My brother had the same problem.

    Common problem with this is one or two coil packs when bad.

    The coil pack is what sit on top of the spark plug giving each spark plug it's own coil for firing.

    Let me know if I'm right on this one. :)

    When driving and you accelerate moderately engine misses and backfires until you step on gas harder and it shifts down and revs faster

SOURCE: misses during acceleration , rough

Go get the codes ran at auto zone or advance auto parts they will do it for free. If the codes come up as a cylinder miss-fire then it is most likely a coil (being a ford). Write down which cylinder it is. I wouldn't replace any of the spark plugs , useless you have more than 100,000 miles. If you have to replace the spark plugs use BOSH double plautim or better. The cylinder placing is ( as your are looking at the front of the truck) passenger side front to back 1-2-3-4 driving side front to back 5-6-7-8. If you never seen a coil buy one so you know what you are looking for. The coil is held in by a 7mm bolt. Take the bolt out and replace the coil. Problem Solved. Estimated time 20 Mins with 60 dollars per coil.

Where is the egr valve on a 99 Ford expedition


The EGR valve is in a very difficult spot to work on. If the EGR is bad it will set off the check engine light and make the vehicle run rough or stall at idle. It really doesn't make it run rough while driving or accelerating. What are the conditions when the car runs rough?

I have 2000 ford expedition and last few weeks its been making a whistling noise when accelerate, then past few days it's been running rough, idel low and shakes a bit then today check engine ligh


You might check the pulleys that the serpentine belt runs on. Make sure all are free wheeling and not loose or rough or make noise. You would need to remove the belt to check them.

My 2003 Ford Expedition runs rough at idle and the service light started blinking.


it sounds like you need to tune up your vehicle. whenever the service light blinks it usually means you have a miss fire. You can take it to auto Zone to retrieve the code. The code should tell you what cylinder is miss firing.Hope this helps. Please leave comment.

Expedition running rough on acceleration, it's a 5.4L.


running rough means it is misfiring.does it run smoothly without load or at idle?If it does then better check you fuel pressure as the engine needs more fuel under load.
